I'm having trouble flashing my mobo's bios because instant flash isnt a option for my bios version. I wanted to update my bios in hopes of it fixing my issue with my ram not being able to overclock into XMP. Can you please recommend a way to fix this issue.
Thank you

Which BBIOS (UEFI) version are you trying to flash to? Do you mean that when you go to update the BIOS version that Instant Flash is grayed out?
